BOBBIN -WINDER.

SPECIFICATION forming part of Letters Patent No. 365,909. dated July 5,1887.

Application filed February 2, 1886. Serial No. 190,605. (No model.)

To all whom it may concern:

Be it known that I, DANIEL W. Conny, a citizen of the United Gtates, residing at Galena, county of Jo Daviess, and State of Illinois, have invented certain new and useful Improvements in Bobbin-Winders, of which the following is a specification.

This invention relates to improvements in bobbin-winders especially designed for a bobbin having end flanges and sleeved upon a spindle provided with heads, between which the bobbin is confined.

The objects of this invention are to provide a bobbin-winder which shall center the bob-,

1 bin and at the same time prevent the bobbin rotating upon its spindle, whereby the bobbin and its spindle shall revolve with and upon the axis of the shaftpf the bobbin-winder.

A further object is to provide a bobbin- .winder which shall not only center and prevent the bobbin turning on its spindle, but firmly hold the bobbin without exerting a crushing endwisc strain thereon.

These objects are attained by devices illus- 2 5 trated in the accompanying drawings, in

which- Figure 1 illustrates a side elevation of a bobbin-winder embodying my invention,with a bobbin in its operative position therein;

Fig. 2, an enlarged longitudinal sectional view of the same; Fig. 3, a similar and detail view of a modification in the construction of the actuating-shaft of the bobbin-winder; Figs. 4 and 5, end views of the bobbin shown in Figs.

3 5 1 and 2.

Similar letters of reference indicate the same parts in the several figures of the drawings.

Referring by letter to the accompanying drawings, A indicates the supporting bracket 0 or frame of an ordinary bobbin-winder secured to a machine by means of the lugs a e in the usual manner at any suitable point on the machine bed or arm. Loosely journaled in one I end of this bracket is the ordinary spring- 4 5 seated presser,l3, having its operative end projecting toward the center of the said bracket, provided with a slight depression located centrally in the face thereof, and into which de pression seats one end of the shaft of the bobbin, as will be hereinafter more fully described. The construction of this presser is identical with that common to devices of this eharae terthat is to say, on the outer end of the shaft thereof is rigidly secured a thumb-piece,

(l, for withdrawing the head D of the presser from contact with the bobbin-shaft, and also to limit the forward movement of the presser shaft and head when actuated by the spring cushion. The end of the bracket is recessed to receive the said head 1), which, as usual, is of greater diameter than the presser-shaft,and surrounding this shaft, between the presserhead and the rear wall of the bracket, is lo cated a spiral spring, E, for actuating the head and exerting a springtension longitudinally ()5 on the end of the shaft of the bobbin. I may here add that the depression in the face of the head is for the purpose of centering and retaining the bobbin in position during the operation of winding.

In the opposite end of the bracket or frameis loosely journaled a short shaft, F, carrying upon its outer end the usual friction wheel for imparting a rotary motion thereto, and having its inner end projecting beyond its bearing in the bracket enlarged to form ahead, G, the said head and the friction-wheel serving to effectually prevent any end wise shifting of the shaft upon its bearing. This shaft is pref erably-hollowed or bored out to form a recess 8 for reception of a spindle, H, carrying upon its outer end a disk, I, working longitudinally in the enlarged annular recess J in the head G, as clearly illustrated in Fig. 2. Sur rounding the spindle, and confined between 8 the disk I and an annular shoulder near the inner end of the recess, is a spiral spring, K, constituting a spring-cushion for the said disk I, against which one end and the opposite end to that engaging the presser of the bobbino shaftbears.

To permit an endwise movement of the spindle H, and at the same time insure its rotation with the shaft F, the inner end of the said spindle has an elongated notch or offset, 0, into which projects and works a pin, d, which passes transversely through the shaft F,and is rigidly secured thereto. This pin, in connection with the notch, not only serves to insure the rotation of the spindle with the shaft, but also permits an endwise movement of the said Spindle in its socket, and at the same time serves to limit the endwise movement of the said spindle, according to the length of the notch or offset 0, and such limitation is necessary to prevent the disk I on the end thereof projecting beyond the face of the head G. I may'here state, to give a clearer understanding of the operation of the notch c and pin d, that the face of the wall where the notch or offset is made is square or plain, and across this surface projects and works the pin; and it is obvious that any rotation of the shaft F will cause the pin to bear against one edge of the face of the notch, and thereby cause the spindle to rotate therewith.

Between the head B of the presser and the disk I is seated the bobbin-shaft e, carrying rigidly upon either end thereof flanges ff. The recess in the face of the head B, in which seats the end of the shaft 0, serves to center said shaft on that end, while the flange'on the opposite end of said shaft seats upon an annular shoulder, formed in the face of the head I G, and is thereby readily centered on that end,

thus avoidingthe necessity for reee'ssing the disk I.

. Between the flanges ff, and loosely journaled upon the shaft e, is the bobbin h, upon which is wound the thread for the shuttle. The construction and operation of this bobbin are fully described and claimed in Letters Patent No. 323,916, granted to me August 11, 1885, and therefore does not enter as an element in this invention, and is only employed to illustrate the operation of my device, which is especially designed for use in connection with bobbins constructed substantially in the manner j ust described-that is to say, a bobbin having end flanges and sleeved upon a spindle provided with heads between which the bobbin is confined.

The essential object of this invention is to prevent the bobbin rotating independently. of its shaft or spindle during the operation of Winding the bottom in such manner that the bobbin and its spindle shall revolve with and upon the axis of the shaft of the bobbinwinder. I am enabled to do this by employing a pin, 1', rigidly secured to and projecting forward at a right angle from the face of the disk I, which pin passes throughperforations or holes j, formed in the end flange of the bobbin and the flange on the shaft thereof. These holes must necessarily register with each other in order to permit the passage through them of the pin 73, and they may be formed as two circular holes illustrated in Fig. 5, or preferably as illustrated in Fig. 4, in which is shown a circular hole, j, in the flange of the bobbin, with a series of elongated curved slots,

k, formed in the flange fon the bobbin-shaft, and registering throughout their length with the hole j. The employment of these slots obviously facilitates the introduction of the pin into the holej.

It will be observed by reference to Fig. 2 that the pressure or tension of the cushioningspring both in the presser and the actuatingpin, and it is obvious that any rotation of the actuatingshaft carrying the spindle and disk will produce a corresponding rotation of the bobbin and shaft upon the axis of the said actuating-shaft and of the bobbin-winder as a whole. In Fig. 3 I have illustrated a modificatio of my invention in which the actuatingshaft is solid and the pin i rigidly secured to and projecting from the face of the head G. The shaft of the bobbin seats in a corresponding recess or depression in the center of the face of said head, and is thereby centered and maintained in position. By this construction the end cushion of the bobbin, consisting of the spring-actuated disk I, may be dispensed with; but, as before described, the employment of such a cushion is advantageous in promoting a decrease in the endwise pressure on the bobbin, which tendsto crush and strain the said bobbin, and is therefore a preferred 7 construction.

In conclusion, I may add that it would be no substantial departure from the spirit of my invention to provide a pin-that is to say, a erank-pin-projecting from the .face of the presser-head, and dispense with the one on the actuating-shaft head; and it is thought that such a construction is so obviously within the scope of my invention that it is unnecessary to illustrate this point in the drawings.

It is admitted that a swinging and solid shaft reciprocating in its bearing and held therein and made yielding by an angular spring pressing against its outer end has, before my invention, been provided with a crank-pin in its inner end; but this endwise yielding of the shaft renders the moving of the winder-pulley on the fly-wheel of the machine unstable and the actuation of the bobbin irregular and uncertain, which objections are materially increased by the swinging feature of the entire structure; also, that a bobbin-winder in which a spring-actuated sleeve on the actuatingshaft, having its inner end closed, has, before my invention, been provided with a crankpin; but as such sleeve is between the shaft and the journal-box; and therefore subject to the entire friction of said box when the shaft is revolved, oil, dirt, grit, &c., not onlyaccumulates in the spring-chamber and between the shaft and sleeve to such an extent as to destroy the operation of the spring, but the friction between the sleeve and the box,when the bobbin is revolved at the ordinary but high velocity, frequently causes a compression of the spring and an accidental discharge of the bobbin during the winding operation, and besides this, the yielding function of the shaft r to mm a

promotes uncertain contact between the driving-wheel of thebobbin holder and the flywheel of the machine, and to such an extent that if the driving-wheel is not thrown out of contact its revolutions are extremely unccrtain and irregular.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-
